Entrance mats in revolving doors are becoming increasingly popular. The only choice you really have is to use stainless steel. We now offer both linear and radial grids with air baffles to prevent air flow underneath. If you think using a mat in the revolving door eliminates the need for one inside the building, your wrong. Use our Peditred shown in the Public Area section. Otherwise the maintanence department will throw down those black and red rental mats... of course over your nice stone floor you didn’t want to disrupt during the design phase!
